As DTM CRS3035RES50000mN2650000E4450000 elevation grid 1 m cut-off date 15.9.2022

One of 55 tiles comprising a complete 1-meter resolution digital terrain model covering Austria. The ALS DTM elevation grid was recorded using airborne laser scanning technologies and describes the bare earth surface without vegetation. This tile is a cooperation product of Austrian federal and state spatial data providers, with a cut-off date of September 15, 2022.

Use Cases

• Hydrological modeling based on the 1-meter resolution bare-earth elevation data.
• Infrastructure planning and line-of-sight analysis using the detailed terrain surface.
• Environmental change detection by comparing this DTM with other temporal snapshots.
• Creating derivative maps like slope and aspect from the regular grid of georeferenced height points.

Strengths

• High spatial resolution of 1 meter for detailed terrain representation.
• Covers the entire territory of Austria as part of a 55-tile mosaic.
• Explicitly models the bare earth surface, excluding vegetation, which is useful for foundational geospatial analysis.
• Data is georeferenced in European coordinate reference systems for interoperability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified beyond the stated cut-off date.
• Row count and total file size are unknown, which may limit suitability assessment for large-scale processing.
